    Effect of eDNA metabarcoding temporal sampling strategies on detection of coastal biodiversity by Maelle Sevellec, Anaïs Lacoursière-Roussel, Eric Normandeau, Louis Bernatchez, Kimberly Lynn Howland

    Published 2025-02-01
    “…However, we have limited knowledge of whether samples collected during discreet temporal periods depict holistic ecosystem changes over longer time spans.MethodsHere, we show how eDNA community structure varies across repeated sampling events at different temporal scales ranging from years to months to days at an Arctic coastal site, Churchill (Canada), using metabarcoding analyses of water eDNA samples with four universal primer pairs (two primers in COI and two in the 18S rRNA).ResultsDaily variations were highly dynamic and less structured, likely due to the stochastic nature of estuarine ecosystems, but there was a clear annual consistency in eDNA communities with a high proportion of shared taxa between years. …”

    Constructing habitat networks to protect endangered migratory birds in the Jiaozhou Bay area by Xinyu Liu, Ye Zhao, Lin Fan

    Published 2025-01-01
    “…Our findings revealed that (1) land use, food source, and human disturbance are the three primary environmental variables influencing habitat suitability; (2) habitat networks in the bay area are centered around estuarine wetlands and mudflats, with a fragmentation trend of habitats from the ocean to inland areas; and (3) habitat patches and corridors closer to the ocean have higher centrality levels in the network compared to those further inland. …”

    Cross-checking OSL ages from different grain sizes to improve chronological reliability in deltaic environments: an example from the Yangtze River Delta by Xuemei Wang, Xiaomei Nian, Weiguo Zhang, Fengyue Qiu

    Published 2024-12-01
    “…The variability in luminescence sensitivity reflects changes in sediment provenance and depositional conditions between estuarine and deltaic environments. OSL ages indicate that the sedimentary evolution of the Yangtze River Delta progressed through distinct phases: rapid accumulation during the early Holocene (10–7 ka) driven by rising sea level and valley infilling; reduced sedimentation during the middle Holocene (7–3 ka) related to a dry climate in the catchment; and accelerated deposition in the late Holocene (3 ka–present) associated with enhanced fluvial input linked to intensified human activities. …”

    Using Sediment Bacterial Communities to Predict Trace Metal Pollution Risk in Coastal Environment Management: Feasibility, Reliability, and Practicability by Yuanfen Xia, Jiayuan Liu, Xuechun Yang, Xiaofeng Ling, Yan Fang, Zhen Xu, Fude Liu

    Published 2024-11-01
    “…Therefore, a tidal gate-controlled coastal river was selected to test the distribution and accumulation risks of Al, As, Cr, Cu, Fe, Mn, Ni, Sr, and Zn in the catchment area (CA), estuarine area (EA), and offshore area (OA). Associations between TMs and bacterial communities were analyzed to assess the feasibility of using bacterial parameters as ecological indicators. …”

    A New Concept Proposal of the Tidal Level Designed for the Security of Coastal Levee during Storm Surge — Taking the Lingdingyang Estuary as an Example by LI Bin, HE Yong, FANG Shenguang

    Published 2021-01-01
    “…Based on the analysis of the design frequency tidal levels,storm surge water increase and flood inflow upstream of control stations in Lingdingyang Estuary over years,it showed that the tidal levels of designed frequency of 0.5%~2.0% raised from 0.2 to 1.0 m in recent years,the extreme storm surge elevations exceed 2.5 m commonly,and the current tidal level difference of adjacent design frequency was less than 0.2 m.During the emergence of the extreme storm surge elevation in the estuary flood upstream would not be appeared simutaneously,while the moderate tide was most likely encounterred.Therefore,there were some problems in the application of design frequency tidal levels in estuarine waters,such as the small tidal level difference between adjacent frequencies,the severe frequency jump of tide level during strong typhoon,and the failure to directly reflect the leading role of the extreme storm surge elevation in the elevation design of coastal levee.The concept of the tidal levels designed for storm surge security of coastal levee was proposed in the paper,which were composed of multi-year average high tidal level and the maximum extreme storm surge elevation,clearly and easily to be used.It highlights the main role played by coastal levee to resist the disaster by strong storm surge.The calculated values were close to and slightly more than the designed tidal levels of 100~200 year return period of main stations in the mouth of Lingdingyang estuary,Shiziyang water area and delta river network area after reviewed in 2020,proving its safety and reliability.The reviewed tidal levels of designed frequency in the Chiwan station in 2020 were likely too high by analysis preliminarily.The tidal level designed for storm surge security of coastal levee could be widely used in reinforcement design,safety risk assessment in storm surge and storm surge disaster warning and response.…”

    Diet of the blue crab (Callinectes sapidus) during range expansion in Great Bay Estuary, New Hampshire by Kelsey A. Meyer-Rust, Alyssa Strickland, Bo-Young Lee, Joseph L. Sevigny, Gabriela Bradt, Bonnie L. Brown

    Published 2024-12-01
    “…Using metagenomics to analyze the diet of blue crabs as they establish viable populations in GBE will be a useful tool for predicting how these range expanding organisms are interacting within this important estuarine ecosystem, which will promote sustainable development by informing end users who may be affected by these crabs to help them meet their needs in the present and future. …”
